Methane (CH4) at 25oC and 1 atm enters a well-insulated reactor and reacts with air entering at the same conditions. For steady-state operation, negligible effects of ke and pe, and negligible pressure loss, plot the temperature of the combustion products against equivalent ratio ranging from 0.5 through 3.0.
(a) Assume complete combustion with PG mixture model,
(b) Assume complete combustion with IG mixture model,
(c) Assume equilibrium combustion with IG mixture model and having CO2, H2O, N2, O2, NO, OH, CO, O, H2 and H in the products mixture. For part (c), also plot the mole fraction of CO and NO in the products against the equivalent ratio.
